class_docstr: Latent Variables Class
  
  Holds latent variable objects and contains method for latent variable manipulation. Latent variables are 
  referred to as z as shorthand. This is convention in much of the literature.
code: def get_z_starting_values(self, transformed=False):
      transforms = self.get_z_transforms()
  
      values = np.zeros(len(self.z_list))
      for i in range(len(self.z_list)):
          if transformed is True:
              values[i] = transforms[i](self.z_list[i].start)
          else:
              values[i] = self.z_list[i].start
      return values
